Yea, he doesn't realize that a stock cubed 500+ RWHP engine is going to idle like a piece of ****....probably smell terrible of gas and exhaust when sitting still and hard to tune.......unless you like monster lope....then its cool.

ok so the consensus is build a stroker then. that will work. I have seen several f-bodies that have had 408's and they were less than inpressive and I have seen some very impressive ls2's making 450 with as I was told a mild cam(not much lope) that's kinda why I asked this question to the guys I feel know quite a bit. So saying a stroker build what would be a good ci to try for??? oh and by the way I mis-stated a ealier post, meant to say I'm not trying to spray 500 shot. I will only want to spray 200-300 maybe.

yeah if you re going to go threw the process of rebuild you should stroke it.

and 600 is going to be hard to reach and be anywhere near streetable.

for a comparrison my ls3 418 with cnc ported heads and one of the bigger cams LG makes put down 505 hp in a auto GTO so in my manual setup it should see 540 or more with my setup. this is a totally streetable engine however no solid roller or anything but still can run u to 7000 rpms just dosnt make power after 6500 or so

Whats your goal man............your final goal....what type of racing do you want to do with it? Or what FUN?

My friend has a 422ci iron block with an LS6 intake and ported LS6 heads, mild cam somewhere in the 230's, idles very close to stock. It made 535 RWHP. He has been spraying a 300 shot for like 6-7 years with it and its still running like a champ. It makes 880 RWHP on the 300 shot.
He drives around on full time 93 octane....and has a stand alone tank with race gas that feeds the DP system.

Will that make you smile.....

To be streetable set your goal to say 480-520 RWHP. This would be in a 400-416 stroker. If you stick with the manual trans you should have little driveabilty problems. You'll have more with an auto. Do you have all the chassis and suspension parts to handle just the motor HP? Then spraying a 150-300 shot on top of that equals a serious build. Good luck and it will give you a serious smile when finished. I drove my car around town yesterday on full slicks and skinnies it was a blast.

Yes all of the drivetrain is replaced with upgraded parts and so is the suspension. I have put 620 rwhp to it already and no problems. The trans is good for 1000 hp, driveshaftshop.com shaft good for 1000 hp and the shafts are also rated for 1000 hp.

And driving a fun car around on slicks and skinnies is always fun

Not positive....but he had it built the same year I had my 427ci built....2002. So whatever LSx "type" iron block there was back then.

If you're talking about setting it up to strictly drag race....you know with that HP you're talking about an 8 second car, right?

in an f body it most certainly would be but in a GTO high to mid 9's.. That's the down side of owning a GTO they are heavy *** pigs and have a poor rear axle set up from the factory

What intake do you plan on running. Good luck with the build.

I'm thinking carbed type but injected, soild roller, plate type TB , 2" headers, 4 speed jerico and rev it to 8k+, and boom 600+rwhp. Thats the ticket and possibly my next build. Gotta love NA HP.

Not an LS2, but a very mild build nonetheless. LS7 crate motor, Katech cam, long tubes, Marcella sheetmetal intake and 102 throttle body. The intake and throttle body picked up 60 rwhp. With a little head work, I imagine it would go right on past 600 rwhp, and it drives very, very nice.

Nah. Owner built it himself in his garage. I can only take credit for the tuning.
